The best overall college beer. Good taste, yet you can drink it till the sun comes up, and its only like 13 bucks for 30 of them.
I woke up at 1pm and drank keystone till 6am while smoking blunts of the chronic every couple hours but didnt pass out because keystone allows you to consume record amounts of beer and feel fine the next day.

The keystone is known as a stone that holds certain materials together in a bridge or arch. The keystone is also in correlation with the commonwealth of Pennsylvania (PA) including road signs and government department logos. Pennsylvania was named "The Keystone State" after its pivotal role in the civil war between the north and south. This unofficial term can also be used to refer to a native Pennsylvanian or it can be used as a sentence enhancer in multiple forms/tenses such as Keystonin, Keystoned, etc...
